Observed Mars last night and saw the ice cap and a bit of detail, but just mucking around I put this montage together showing roughly the eyepiece view through my telescope at various magnifications. Mars is around 13 arcseconds diameter at the moment. I don't use wide-angle EPs, and these would be typical views through ordinary plossls etc. 225x is about maxed-out for my 4.5" scope!
Enlarge to full size in screen because it's quite wide - hope it's of interest.
Cheers -
